| Abstract: | A research is made on the habitat, internal distribution pattern and quantitative character of Davidia Involuarata in Xingdoushan Protected Region. The results show that its habitat is rather particular and its distribution is characteristic of contagious and duster round. The population structure is stable and the wirner index is high,without natural pure stand. The main breed conutermeasure is root germination. |
